IMPROVEMENT INWINDMILLS.

Specification forming part of Letters Patent No. 171,630, dated December25, 1875; application filed March To all whom it may concern:

Be it known that I, ARTHUR T. PAGE, of Garden Prairie, in the county ofBoone and State of Illinois, have invented a new and usefulImprovementin Windmills and I do hereby declare that the following is afull and exact description of the same, reference being had to theaccompanying drawings, and to the letters of reference marked thereon.

Figure 1 represents a perspective view of my improved windmill, andFig-=2 represents a rear elevation of a portion of the same.

Similar letters of reference denote corre sponding parts'in bothfigures.

The invention relates to a novel arrangement of means for holding theWheel in the face of the wind, and for deflecting the same therefrom, asthe force of the Wind increases beyond what is required for rotating thewheel with the desired velocity, and to certain details of constructionand arrangement of parts hereinafter fully set forth.

In the drawings, Arepresents the tower, which may be of any usual orpreferred construction. The upper part of this tower is provided withsuitable bearings for the reception and support of a hollow verticalcylinder, B, which forms the pivot on which the windmill, as a whole,turns to accommodate itself to the direction of the wind, and centrallythrough which the pump-rod 1) passes, said rod further passing throughsuitable guides, as at a. At difl'erent points in its length, near theupper end of this hollow pivot B, is secured a horizontal stud or studs,carrying a friction-roller, b, which rests on the top plate A, thisroller, where but a single one'is used,

sleeve the collar B is provided with an angleiron socket, c, in which issecured the upright wooden block 0, to which, midway of its height,thevane D is rigidly secured, as shown.

cured, in any suitable manner, an angle-iron,

is provided with a sleeve, E,arran ged vertically over the pivot B, ornearly so. The sleeve E affords bearings for a vertical shaft or pivot,which is retained in position therein by an enlarged head or collar,F,'at its upper end. The lower end of this shaft has a yoke or archedplate, G, permanently secured to it midway of its length, and thedepressed ends of this yoke or arch-plate are provided, each, with asleevebearing, g, in which the wind-wheel shaft H is mounted, saidshaft, between its bearings g, being provided with a crank at h, throughwhich motion is imparted to the pump-rod. To the outer projecting end ofthe crankshaft H the wind-wheel I is rigidly connected, said wheel, bypreference, being of that class known as the solid wheel, in which theblades are rig-- idly attached at the preferred angle ofobliqut' jty.The central radial arms or spider l are 1 dished on the inner face ofthe wheel, in such manner as to bring the weight of the wheel as nearlyas practicable into the same vertical plane with the vertical pivots ofthe wheel, thereby reducing the tendency to .crampthe pivots in theirbearings. The collar F on the upper vertical pivot ,is provided with atoothed beveled segment, f, and the sleeve E, in which said pivot orshaft has its bearings, has a horizontal stud-shaft, 0 projecting fromit on one side, upon which is -mounted a sleeve, K, the inner end ofwhich has cast upon it a perpendicular arm, is, with a cross-head, 7c,the inner face of which is pro vided with a beveled segme11t-rack,j",the teeth of which engage with the teeth of the segment f,'for vibratingthe rack-pivot F. To the rear face of the sleeve K is secured alever-arm, L, upon which is a sliding weight, L, by the adjustment ofwhich the wheel, through its connection therewith by the pivot F,segment f and f, and sleeve K, may be held to the wind with any requiredpower. To the upper end of the pivot F is permanently secured -ahorizontal arm, M, extending rearward at right angles to the plane ofthe wind-wheel, or thereabout, and to the rear end of thisarm atransverse bar, M, .is secured, to which a number of slats, m, areconnected,

To the upper end of .this block O is firmly se- E, the outer end of thehorizontal arm e of which said slats being set obliquely to the planeofthe wind-wheel, as shown, andserving, as the force of the wind isincreased beyond what is requisite for giving the desired velocity tothe wheel, to deflect the wheel or turn it onits pivot F slightly awayfrom the wind, in which position the direct action of the wind upon thewheel itself will serve to further turn it out of the action of or awayfrom the wind,

swinging it around on its pivot F toa position 1 more or lessapproaching aplane parallel with the "ane, according to the force of thewind. In this movement the segment f, acting on i the rack j, and thencethrough the sleeveK on the arm L, raises the weight L, which steadilyresists the deflection of the wheel, andcauses it to return more or lessdirectly into the face of the wind as the force of the latter abates.

Thus far it will be seen that the action of the wheel is automatic. Forplacing it under thecontrolof the attendant on the ground, a lever, P,is pivoted loosely on the outer end of the stud-axle 0 from the shortarm 10 of l which a. cord, q, extends downward through thetubular shaftB, and is connected at its lower end with a lever, Q, near the ground,The long arm P of this lever is bent at 10 into an angular or cranlrform, reaching under the weighted arm L, which vibrates. on the samecenter e,as explained. This arm 1? has an adjustable weight secured toit sufficient to counterbalance the weight of the cord g and lever Q,and to remove it from contact with the arm L, as shown, so as to leavethelatter unobstructed in its automatic action, as explained, exceptwhen it is desired to turn the wheel away from the action of. the windby hand, when the attendant, by pressing down on lever Q, raises: thelong arm of lever P, i bringing it up into contact with the arm L,

when, by a continued movement of the lever P, thearm Iu will beraised,turning the-wheelsh'aft on its vertical pivotF, through therackconnection described...

The lever Q may be locked inthis depressed position-for holding thewind-wheel wholly or 1 partially out of the. face of the windby a rackand pin, or any suitable device for the purpose.

Upon one of the sleeve-bearings g, or to any convenient point on theyoke G, is se-. j

cured a transverse stop-bar, R, the ends of which strike against theupright portion ot the supporting-iron E,-and limit the move i ment ofthe wheel relatively to the vane on the pivot F, within an arc of acircle of ninety degrees, or from a position in which thefacc 1 ofthewheel is at right angles to the vane, to.

one in which it is parallel therewith, or nearly so, and vice versa.

cramp the latter in its bearings, and this is ina measure obviated bythe arrangement of i the friction-roller b, as explained. For furtherovercoming this an arm, S, is projected from the collar B, and rigidlyconnected therewith on the side opposite to the standard 0 and to thevane, and'upon this isplaced a sliding weight, S, which may be set at,anydesired point, for balancing the weight of the vane and block,andstandard 0.

Parts of the mill and of its supporting-tower not specifically describedabove may be of any usual construction.

The mill has been described with reference 1 to its. application fordriving the pump-rod; but it will: be obvious that it may be used forany of the purposes to which this class of wind-wheels are applicable.
